Corneal transplant is a surgical procedure to replace part of your cornea with corneal tissue from a donor. It can improve vision, reduce pain, and help with the appearance of a damaged or diseased cornea. There are two main procedures for corneal transplants; 1) where the entire cornea is replaced, and 2) where specific layers of the cornea are replaced.
Corneal transplants have relatively good success rates compared to most tissue transplant procedures. It does carry the risk of graft rejection, inflammation and secondary pathology in some cases. Surgeons outweigh the risks to benefits prior to recommending surgery.
